LED Status
Description
Alarm LED (ALM)
Off
The router is operating correctly.
Steady red
An alarm has occurred.
Clock synchronization
LED (SYNC)
Steady green
•
Both PTP and network synchronization are
configured. The time and frequency have been
synchronized.
•
Network synchronization is configured and a
non-local clock source is taken as the clock
reference.
•
Network synchronization is configured but no
non-local clock source is specified. The system
clock is operating in freerun state.
Steady yellow
•
Clock source priorities are configured but non-local
clock sources cannot be reached. The system
clock is operating in holdover or freerun state.
•
Both PTP and network synchronization are
configured but no clock source is available. The
system clock and the PTP clock are operating in
holdover or freerun state.
Off
The system clock has not been initialized.
